Abstract: An article of wearing apparel such as a rigid opaque hat or a multi-layer belt has light emitting diodes mounted therein for being viewed, the terminals of the diodes and the circuitry for controlling the same being concealed within the article of apparel or on the person of the wearer. Control circuitry includes an electronic clock which sends electric pulses to an electronic counter, the output of which passes through a decoder which controls which diodes are sequentially illuminated to create an illusion of motion for getting the attention of others or for providing a type of theatrical ornamentation for the user.
